What is a Pulse Arc Welder?
A pulse(d) arc welder is a special case of a Tungsten Inert Gas (TIG) welder. In TIG welding a sharpened tungsten electrode is used in combination with electrical power to start and sustain an high temperature plasma stream – an arc. This plasma arc is used as a heat source to melt the work piece metal. Filler metal can also be added to build up joints and create strong and reliable weld “beads”, or weld seams. TIG welders can use AC (alternating current) or DC (direct current) energy to initiate the plasma arc. Sunstone Engineering has chosen to build on our extensive experience with DC welding technology. The Orion uses industrial capacitive discharge technology to produce the pulse arc weld. AC wall voltage can vary up to 20% during the day. Capacitive welders have the advantage, over AC technologies, of precisely storing energy before the welding process. This means that the Orion will produce a repeatable weld independent of AC power fluctuations. The Orion pulse arc welder is a m
